A headset communication method under a loud-noise environment and a headset are disclosed in the invention. The method comprises: reducing intermediate and high frequency noise entering an ear canal with an earplug, and shunting intermediate and low frequency noise with an externally connected cavity in parallel connection with the ear canal; picking up sound in the ear canal and an leak-in environmental noise signal with an internal microphone, and picking up the environmental noise signal with an external microphone, using the external microphone signal as a reference signal, and obtaining a transmitter side signal of the headset after eliminating the noise component in the internal microphone signal and reserving the voice component; after adopting a sound dynamic compression technology to perform sound pressure level attenuation and compensation processing on the signal picked up by the external microphone, compressing the sound pressure range of the signal to be acceptable by human ears, and playing the signal with the receiver of the headset along with the receiver side signal received by the headset. By means of the technical solution of the present invention, hearing protection, voice enhancement and tridimensional environment monitoring function can be achieved comprehensively under the loud-noise environment. |
